Gunner was on Eukanuba when we first got him. His eyes just poured all the time and his coat was dreadfully dull. I got him switched over to Blue and his coat improved significantly. Well now he's on a combo of ZP, S&C, and raw (mostly chicken, some deer). His coat is just gorgeous and shiny. He still has runny eyes but not nearly like when we got him. I could tell if he were a lighter color he would have bad tear staining. So is this normal? Or is it a sign of an allergy? He does scratch a little. I don't think it is fleas since I've not seen any or any flea dirt. I did bath him in a flea shampoo a few days ago to be on the safe side (which made his skin super flaky).
